PHARMACEUTICAL FORM Film-coated tablet (tablet). authorised Green, pentagon-shaped, film-coated tablet of dimensions 8.9 mm x 8.7 mm, debossed with “GSI” on one side of the tablet and “85” on the other side of the tablet. 4. CLINICAL PARTICULARS longer 4.1 Therapeutic indications Vitekta co-administered with a ritonavir-boosted proteaseno inhibitor and with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus-1 (HIV-1) infection in adults who are infected with HIV-1 without known mutations associated with resistance to elvitegravir (see sections 4.2 and 5.1). 4.2 Posology and method of administration Therapy should be initiated by a physician experienced in the management of HIV infection. product Posology Vitekta must be administered in combination with a ritonavir-boosted protease inhibitor. The Summary of Product Characteristics for the co-administered ritonavir-boosted protease inhibitor should be consulted. The recommended dose of Vitekta is one 85 mg tablet or one 150 mg tablet taken orally once daily with food. The choice of dose of Vitekta depends on the co-administered protease inhibitor (see Table 1 and sections 4.4 and 4.5). For use of the 150 mg tablet, please refer to the Summary of Product Characteristics for Vitekta 150 mg tablets. Medicinal Vitekta should be administered once daily as follows: - Either at the same time as a once daily ritonavir-boosted protease inhibitor - Or with the first dose of a twice daily ritonavir-boosted protease inhibitor. 2 Table 1: Recommended dosing regimens Dose of Vitekta Dose of co-administered ritonavir-boosted protease inhibitor atazanavir 300 mg and ritonavir 100 mg once daily 85 mg once daily lopinavir 400 mg and ritonavir 100 mg twice daily darunavir 600 mg and ritonavir 100 mg twice daily 150 mg once daily fosamprenavir 700 mg and ritonavir 100 mg twice daily There are no data to recommend the use of Vitekta with dosing frequencies or HIV-1 protease inhibitors other than those presented in Table 1. Missed dose If the patient misses a dose of Vitekta within 18 hours of the time it is usually taken, the patient should take Vitekta with food as soon as possible and resume the normal dosing schedule. If a patient misses a dose of Vitekta by more than 18 hours, and it is almost time for their next dose, the patient should not take the missed dose and simply resume the usual dosing schedule. authorised If the patient vomits within 1 hour of taking Vitekta another tablet should be taken. Special populations Elderly No data are available on which to make a dose recommendation for patients over the age of 65 years (see section 5.2). longer Renal impairment No dose adjustment of Vitekta is required for patients with renal impairment (see section 5.2). no Hepatic impairment No dose adjustment of Vitekta is required in patients with mild (Child-Pugh Class A) or moderate hepatic impairment (Child-Pugh Class B). Elvitegravir has not been studied in patients with severe hepatic impairment (Child-Pugh Class C) (see sections 4.4 and 5.2). Paediatric population The safety and efficacy of elvitegravir in children aged 0 to less than 18 years have not yet been established (see section 5.1).product No data are available . Method of administration Vitekta should be taken orally, once daily with food (see section 5.2). The film-coated tablet should not be chewed or crushed. 4.3 Contraindications Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. MedicinalCo-administration with the following medicinal products due to the potential for loss of virologic response and possible development of resistance (see section 4.5): • anticonvulsants: carbamazepine, phenobarbital, phenytoin • antimycobacterials: rifampicin • herbal products: St. John’s wort (Hypericum perforatum) 3 4.4 Special warnings and precautions for use General While effective viral suppression with antiretroviral therapy has been proven to substantially reduce the risk of sexual transmission, a residual risk cannot be excluded. Precautions to prevent transmission should be taken in accordance with national guidelines. The use of Vitekta with HIV-1 protease inhibitors or dosing frequencies other than those presented in Table 1 may result in inadequate or elevated plasma levels of elvitegravir and/or the co-administered medicinal products. Resistance Elvitegravir-resistant viruses show cross-resistance to the integrase strand transfer inhibitor raltegravir in most cases (see section 5.1). Elvitegravir has a relatively low genetic barrier to resistance. Therefore, whenever possible, Vitekta should be administered with a fully active ritonavir-boosted protease inhibitor and a second fully active antiretroviral agent to minimise the potential for virologic failure and the development of resistance (see section 5.1). Co-administration of other medicinal products authorised Elvitegravir is primarily metabolised by CYP3A. Co-administration of Vitekta with strong CYP3A inducers (including St. John’s wort [Hypericum perforatum], rifampicin, carbamazepine, phenobarbital and phenytoin) is contraindicated (see sections 4.3 and 4.5). Co-administration of Vitekta with moderate CYP3A inducers (including, but not limited to, efavirenz and bosentan) is not recommended (see section 4.5). Due to the need for co-administration of Vitekta with a ritonavir-longerboosted protease inhibitor, prescribers should consult the Summary of Product Characteristics of the co-administered protease inhibitor and ritonavir for a description of contraindicated medicinal products and other significant drug-drug interactions that may cause potentially lifeno-threatening adverse reactions or loss of therapeutic effect and possible development of resistance. Atazanavir/ritonavir and lopinavir/ritonavir have been shown to significantly increase the plasma concentrations of elvitegravir (see section 4.5). When used in combination with atazanavir/ritonavir and lopinavir/ritonavir, the dose of Vitekta should be decreased from 150 mg once daily to 85 mg once daily (see section 4.2). Co-administration of Vitekta and related active substances: Vitekta must be used in combination with a ritonavir-boosted proteaseproduct inhibitor. Vitekta should not be used with a protease inhibitor boosted by another agent as dosing recommendations for such combinations have not been established. Boosting elvitegravir with an agent other than ritonavir may result in suboptimal plasma concentrations of elvitegravir and/or the protease inhibitor leading to loss of therapeutic effect and possible development of resistance. Vitekta should not be used in combination with products containing elvitegravir or pharmacokinetic boosting agents other than ritonavir. Contraception requirements MedicinalFemale patients of childbea ring potential should use either a hormonal contraceptive containing at least 30 µg ethinylestradiol and containing norgestimate as the progestagen or should use an alternative reliable method of contraception (see sections 4.5 and 4.6). Co-administration of elvitegravir with oral contraceptives containing progestagens other than norgestimate have not been studied and, therefore, should be avoided. Patients using oestrogens as hormone replacement therapy should be clinically monitored for signs of oestrogen deficiency (see section 4.5). 4 Opportunistic infections Patients receiving Vitekta or any other antiretroviral therapy may continue to develop opportunistic infections and other complications of HIV infection, and therefore should remain under close clinical observation by physicians experienced in the treatment of patients with HIV associated diseases. Patients with HIV and hepatitis B or C virus co-infection Patients with chronic hepatitis B or C treated with antiretroviral therapy are at an increased risk for severe and potentially fatal hepatic adverse reactions. Physicians should refer to current HIV treatment guidelines for the optimal management of HIV infection in patients co-infected with hepatitis B virus (HBV). Liver disease Elvitegravir has not been studied in patients with severe hepatic impairment (Child-Pugh Class C). No dose adjustment of Vitekta is required in patients with mild (Child-Pugh Class A) or moderate hepatic impairment (Child-Pugh Class B) (see sections 4.2 and 5.2). Patients with pre-existing liver dysfunction, including chronic active hepatitis, have an increased frequency of liver function abnormalities during combination antiretroviral therapy (CART) and should be monitored according to standard practice. If there is evidence of worseningauthorised liver disease in such patients, interruption or discontinuation of treatment must be considered. Weight and metabolic parameters An increase in weight and in levels of blood lipids and glucose may occur during antiretroviral therapy. Such changes may in part be linked to disease control and life
